History

The Tokyo Underground Railway (which built the Asakusa-Shimbashi section of the Ginza Line) opened a station here on December 24, 1932, when they extended the line south to Kyōbashi. On September 1, 1941, they merged with the Tokyo Rapid Railway to form the Teito Rapid Transit Authority.

The next development was the opening of Edobashi Station on February 28, 1963, when Toei Line 1 was extended to Higashi-Ginza. Transfer was allowed between the two lines here, but the complex only became a true interchange when the Tōzai Line station opened on September 14, 1967.

Toei Line 1 only received its name - the Asakusa Line - on July 1, 1978, and Edobashi station changed its name on March 19, 1989 (out of fear that it would be confused with Edogawabashi Station on the Yūrakuchō Line, which opened in 1974).

Station layout

The Ginza Line station originally opened as an island platform serving two tracks, but overcrowding prompted the construction of a side platform serving Shibuya-bound trains in 1984. Today the island platform serves only Asakusa-bound trains, and the Shibuya side of the platform is fenced off.

The Tōzai Line station consists of an island platform serving two tracks, while the Asakusa Line station consists of two side platforms with two tracks between them. At the Asakusa line station, passengers must choose their direction before passing through the ticket gates.
